Inspired by Zen and Japanese calligraphy scrolls, ketsudo is a word game based on the fact that Japanese text is written top to bottom and English is written left to right – and objet trouvé (found object).

The left to right text spirals around the top to bottom text, which is missing. Find the top to bottom text and the whole puzzle makes sense. If you can solve this puzzle, you understand how it works

The top to bottom text always takes precedence with spacing. And the spacing will show how many words the solution is. The spacing of the left to right word(s) may be displaced by the solution (app with ads):

Occasionally a forward slash “/” in a puzzle indicates the start of a new word. But it is not used every time – mostly the next line down could indicate the start of a new word. As with crosswords, apostrophes in the solutions are ignored.

When a puzzle is successfully completed the ketsudo seal appears, with a bell sound. Swipe between puzzles or use the arrow keys < > top left. Hold the arrow keys to fast forward/back 10 puzzles at a time.

On the keyboard the ‘?’ key will insert a missing letter, either randomly or on the missing letter you have selected. Selected missing letters will show the underscore line in red. To select any letter or space, just touch the underscore. In this example, all the letters were found with the ‘?’ key. (not the idea of the game!) (app without ads)

If you use the ‘?’ key you will lose a point. The puzzles are bundled into sets of 100, and the home page will give the cumulative score for each set of 100.  Therefore, if you complete all the puzzles without using ‘?’ your score will be 100%.

The puzzles range from very simple to very difficult. The clue text and solution will have some relationship; funny, serious, sad, poetical, surprising, cheeky, rude….  Reset puzzles with the button top right, where you can also turn off the sound.

New sets of 100 puzzles can be purchased from the home page for 0.99p, and then adverts will disappear*.
